Render part of a file in eevee part in cycles

I have a file that needs parts to be renders in EEVEE but some other parts in Cycles, how is best to do this. Most of the file needs to be rendered in EEVEE, the only part that needs to be rendered using Cycles is a glass texture I created using IOR = 1.330 and Alpha = 0.216 for this to render as the correct texture it needs to be rendered in Cycles.

Why not just render with cycles?

I do not believe what you are requesting is possible. Only thing I can think of is to layer the scene. Make 2 renders, one evee and one cycles, then import into photo editor and place the layers for the final.

You can separate the scene into two renderings, render it using Holdout, and synthesize it.
